Vampire batteries. Not kidding.

This is extremely cool and no, it doesn’t require hooking the undead into a wall socket.

Researchers at the University of British Columbia have developed a fuel cell that feeds on human blood. While this sounds utterly gross, it has wonderful uses for things like pacemakers, which currently require surgical battery replacement. Basically, pop one of these babies in, and you’re good to go as long as there’s blood in your veins.

This fuel cell runs on the natural sugars in the blood. Yeast feeds on the blood sugars and creates electricity.

My question is, what happens if you eat a whole box of apple fritters? Do you give yourself a shock?
